Wrestling

Men compete in both freestyle and Greco-Roman wrestling, while women compete only in the freestyle form of the sport.

In both disciplines, men compete across six weight divisions from under 57kg to up to 125kg. The women's divisions range from under 48kg to up to 75kg.

The aim of both Greco-Roman and freestyle wrestling is to pin the opponent's shoulders to the mat for long enough to be in control.

A match can also be won by moving 10 points ahead of an opponent, or by scoring more points than the opponent over the course of the bout. If required, the bouts take place over two three-minute rounds, with a 30-second break between each round.

If the scores are tied at the end of the second round, or neither competitor has scored three points, the match is extended into three minutes of extra time.

If the deadlock is not broken after extra time, or each competitor has still scored fewer than three points, the referee, mat chairman and judge take a vote to determine the winner.

Wrestlers score points for a range of holds and throws. One point is awarded for a takedown, which throws the opponent off his feet, landing in front of the thrower.

In Greco-Roman wrestling, an attacking competitor must follow his opponent to the mat as he throws him.

Two points are awarded if a competitor turns his opponent's shoulders so his back is angled towards the mat — in what is known as the danger position.

Another point is awarded if a wrestler keeps his opponent in the danger position for five seconds or more. Taking an opponent off his feet and into the danger position in one movement is worth three points.

Five points are awarded for throwing an opponent in the air, or for a grand amplitude — where the opponent's centre of gravity is lifted higher than the attacking wrestler's.

Points are also earned if an opponent is judged guilty of passivity. This involves failing to attempt to wrestle, or impeding the opponent from wrestling.

A warning is given, and a second warning means a point is given to the opponent.
